FBCS-Series, A Lighter Touch--Zero Input Power

[Spherenot]

Try this: FBCS-22-2D.A

Bill of Materials

1. (1) oscilloscope, with (1) probe
2. (1) 25 ft. length, 22 gauge solid, "hook-up & lead wire"
3. (2) old CDs, (Revision A: Use clear CDs; less the metallic layer.)
4. adhesive tape (optional)
5. super-glue, cyanoacrylate (optional)

Assembly  (I basically made a flat-bifilar-coil sandwich.)

1. Start with one slice of CD.

2. Completely cover surface of CD with wire as shown in Figure 2 of Nikola Tesla's, US Patent 512,340, "COIL FOR ELECTRO MAGNETS."

3. I used paper tape, cyanoacrylate glue, bits of skin from my fingertips, and some profanity to fix the wires to the CD.  It worked but there must be a better way!  I started at the center and worked my way out to the edge, or 'crust.'

4. I then removed most of the paper tape, except adhesive layers stuck to the glue, then I added more glue dressing over the top of the wires.

5. Cover with second slice of CD, weight the top, and wait for glue to dry.

6. Connect wires together as shown in Figure 2 of patent above.  It is simple, but easy to screw-up.  We could get one 'spiral' connected to itself and end up testing only half of the 'embodiment.'  Luckily, the inner and outer edges of the CD are clear, so we can distinguish the outer-spiral wire from the inner-spiral wire.

Now we have a flat-bifilar-coil-sandwich.  Since I used 22 gauge wire and 2 CDs, I will call it the: FBCS-22-2D design.

Testing

1. Connection: There are two ways to place the FBCS-22-2D on a flat surface and two ways to wire it to the 'scope.  We wire it one way and if we do not see results then we flip the FBCS-22-2D over.  If flipping it over is too much for us we could also switch the wires.  But if we flip the unit over and switch the wires we return to the same condition.

In a horizontal configuration, I found reception to be much stronger with the scope leads connected in either one of two ways:

   a.  the red-probe-tip connected at center wire, (outer-spiral wire,) with counter-clockwise rotation as viewed from the top, or

   b.  the red-probe-tip connected at edge, (inner-spiral wire,) wire with clockwise rotation as viewed from the top.

Your results may very in the southern hemisphere there, Lindsay.

Yes, this FBCS-22-2D is inversion sensitive.  Remind us of anything?

2. Oscilloscope Settings: TIME/DIV = 0.1 ?S/D,   (VOLTS/DIV = 5 mV/D),  AC setting

3. My Graticule Results: Sine Wave: DIV/CYCLE = 7 D/C,   (~10 mV p-t-p)

4. Calculate Frequency: (1 C / 7 D)(1 D / 0.1 ?S) = 1,430,000 C/S = 1.43 MHz

5. Search frequency online: "?1.43 MHz which corresponds to the electron gyrofrequency in the Earth?s magnetic field at  200 km altitude."

Of what use is a free 10 mV peak-to-peak sine wave oscillating with Earth's magnetic field?


UPDATE:  Wondering if the aluminum layer in the CDs was helping or hurting, I decided to add CDs two at a time; one on top and one on the bottom of the FBCS-22-2D.

I find that the strength of this frequency varies from time to time and that my body seems to be an antenna.  When I place my hand over the unit the amplitude will begin to increase at a distance of about two inches and increases two or three fold as my hand comes into contact and I apply more pressure.

If I place a small puddle of water on the top of the unit and just touch the puddle with what is left of my glue-battered finger-tip I get a sudden increase in amplitude as well.

Anyway, as I add the extra layers of CD's to the unit the amplitude gets smaller and smaller with each successive layer.

So, I recommend using the clear CDs from now on.

UPDATE:  I just broke off [removed by breaking] the top CD. [The unit is fine.]

Tonight I am getting weaker signals than last night.  The peak-to-peak was dropping down to about 6 mV and, even though I am using the lowest VOLTS/DIV setting, the sine wave tracking was hard for my scope to follow and I would  intermittently see a wide fizzy band until I placed my hand over the unit, slightly increasing the amplitude, and the sine wave would pop back onto screen.

With the top CD removed I am getting a steady 10 mV peak-to-peak just like last night with the top CD on.

UPDATE: 16/JAN/07

The FBC-30-4W was a failure.  Seven hours winding shot in the ass.  No strong signals detected.

The FBCS-22-2D.A turns out to be accidentally tuned to 4600 kHz AM, not 4300 kHz as originally calculated.

I calculate that I should have seen 6.85 divisions, for 4600 kHz, instead of the 7.0 divisions, for 4300 kHz, that I thought I saw on my scope.  I took a second look and it looks like maybe 6.9 divisions at the least.  Close enough; 2.1% error in my original reading.

I confirmed my theory tonight.  I hooked up FBCS-22-2D.A again to my scope but this time I adjusted to the 2 mS / DIV range.  Pulled my AM radio out of the garage, tuned to 4600 AM and watched my scope.  Guess what?

Video attached just below pictures below. [I need to try to reconvert the video again!  I lost the sound!     The video is useless without sound.  Why can't I upload my "3g2" video clip,... with the sound?  There may never be a video posted here.  Anyway, it showed the mixing signals on the scope "dancing" to the radio station's music.]

Hi,

Thanks for the interesting infos.

Would you place a capacitor of 30-50pF in parallel with your wire endings (just the wires you connect the scope probe to)?
A variable capacitor of 200-500pF would be even better to tune the pancake coil and see if the amplitude of the present 10mVpp changes.
Wonder what formula you used to calculate the frequency of 1.43MHz. Is it included somewhere on the web?

I will check my ultra-limited and disorganized supply of capacitors.

I do not know if we can rightly call unit conversion ratios a fully grown 'formula'.

Very cool.
What about adding a variable Cap to that to turn it into a LC circuit
tuned to resonate at 1.43 MHz ?

Again, I will see what I can do about adding the caps.

For resonance, I was thinking about controlling the length of the wire to a division of the mysteriously calculated wavelength of 688 ft.  Perhaps half at 344 ft., or a quarter at 172 ft.  I can probably fit it on a CD if I use smaller gauge mag-wire.
